Valve characteristicsThis Information Sheet contains valve flow coefficients (accord-ing to IEC 60534-2-3) measured on the SAMSON test bench for all available nominal sizes and flow coefficients KVS for the Type 3241, Type 3251, and Type 3254 Globe Valves as well as for the Type 3256 Angle Valve.The flow coefficients KV are specified for a travel of up to 110 % to indicate the remaining reserve that the valves have.NOTICE! This overtravel cannot be implemented in valves with bellows seal.Note: In the online version of this data sheet, you can click on the KVS or CV coefficient to open a graph of the flow coefficient.
